A few things I want to ask:
- Which e-mail provider?
- Are you sure you didn't typo your e-mail address?
- Did you try resending the e-mail?

I know at least AOL is extremely slow with delivery. Everything else I tested (Hotmail, GMail, even my own ISP) came through pretty much instantly. AOL, however, took ~3 hours (which appears to be purely on AOL's side, as logs stated it all went through successfully, AOL said everything was fine).

If you've yet to receive your e-mail and/or it hasn't been resolved yet, let me know and I'll get on it for you.
